Changes in Balance with Brain Inflammation: Sensitivity in Dual Motor Mechanisms
… constant loading (COPc) and variable loading (COPv) signals in concussed athletes during quiet stance. NCAA Division I athletes participated in comprehensive concussion assessments including quiet stance trials on force plates. COPc and COPv signals were analyzed for average velocity, root mean …

The effect of osteopathic manipulative therapy applied to the lumbar spine on postural stability: a pilot study
… measured by average centre of pressure velocity (COPV) on a vertical force platfrom measurement system. Significant reduction in average COPV was demonstrated during tandem stance for the intervention group with both eyes-open and eyes-closed. No significant changes in average COPV were observed …

Hybrid Rocket Motor Scaling Process
… such as Composite Overwrapped Pressure Vessels (COPV) for use as fuel and oxidizer tanks on rockets promise great advantages in flight performance and manufacturing cost. A small scale COPV, carbon fiber ablative nozzle and a N class hybrid rocket motor were developed, manufactured and tested to …

Cloning and Molecular Characterization of Novel Animal Papillomaviruses
… associated with vaccine-induced carcinomas (COPV); an avian papillomavirus (PePV); an oral papillomavirus of domestic rabbits (ROPV); and the first papillomavirus isolated from a murine species, Micromys minutus, which is associated with carcinomas in the natural host (MmPV). In addition, the …

A Comparison of Strength, ROM, Laxity, and Static and Dynamic Postural Control Between Ankle Copers and Patients With Chronic Ankle Instability
… to the participant’s body mass (N•m-1•kg-1). COPV was reported for the A/P and M/L directions, and TTB measures were reported in seconds (s). The maximum distance achieved during the WBLT was reported in centimeters (cm). Three trials of reach direction of the SEBT (cm), as well as a composite …

Neural Network Burst Pressure Prediction in Composite Overwrapped Pressure Vessels Using Mathematically Modeled Acoustic Emission Data
… in composite overwrapped pressure vessels (COPV) using mathematically modeled acoustic emission (AE) data. The AE data were collected during hydrostatic burst (hydroburst) testing often 15-inch (380 mm) diameter COP Vs. The data gathered during these tests were filtered in order to remove …

A Comparison of Strength, ROM, Laxity, and Dynamic and Static Postural Control Between Those At-Risk and Healthy
… examined with the center of pressure velocity (COPV, m/s2) and time-to-boundary (TTB, s). Ankle dorsiflexion from the WBLT is represented by the distance away from the wall (cm) the foot can slide and still allow the knee to touch the wall while performing weight-bearing dorsiflexion. The …

An Examination of Contributing Factors to Star Excursion Balance Test in Individuals with and without Chronic Ankle Instability
… calculated as the center of pressure velocity (COPV, m/s2) and time-to-boundary (TTB). Ankle dorsiflexion from the WBLT is represented by the distance away from the wall (cm) the foot can slide and still allow the knee to touch the wall while performing closed-chain dorsiflexion. Ankle …
